N-Heterocyclic choline analogues based on 1,2,3,4-tetrahydro(iso)quinoline scaffold with anticancer and anti-infective dual action

2016

Pharmacological effects of biologically active “small molecules” can be improved by their targeted modification, which affects drug delivery and interaction with tumor cells and microorganisms. We aimed to evaluate anticancer and antimicrobial activity of lipid-like choline derivatives modified via simultaneous introduction of tetrahydro(iso)quinoline based pharmacophore system at nitrogen atom and long chain alkyl substituent at oxygen atom. Target compounds were synthesized under phase-transfer catalysis conditions followed by quaternization, and evaluated for cytotoxicity and NO-generation ability on HT-1080 and MG-22A tumor cell lines and NIH 3T3 normal mouse fibroblasts, and screened f…

Mimonoside D: a new triterpenoid saponin from Mimosa diplotricha Sauvalle (Fabaceae)

2021

A new triterpenoid saponin (Mimonoside D: 3-O-��-L-arabinopyranosyl-3��-hydroxyolean-12-en-28-oic acid 28-O-��-D-xylopyranosyl-(1���2)-��-D- glucopyranoside ester (1)) was isolated from the aerial parts of Mimosa diplotricha Sauvalle together with nine known compounds: 7,4���-dihydroxyflavone (2), kaempferol (3), lupeol (4), betulinic acid (5), ��-sitosterol (6), ��-sitosterol-3-O-��-D-glucopyranoside (7), lutein (8), 5,2���-dihydroxy-7,4���,5���-trimethoxyflavone (9) and vitexin (10). Their structures were elucidated on the basis of spectroscopic (1 D and 2 D nuclear magnetic resonance) and high-resolution mass spectrometric data as well as by comparison of their spectral data with those o…

Production and optimization of exocellular lipases produced by Proteus mirabilis

2016

Lipazy są wytwarzane przez rośliny, zwierzęta i mikroorganizmy, ale tylko te pochodzenia mikrobiologicznego są ważne dla przemysłu ze względu na zróżnicowane właściwości enzymatyczne i specyficzność substratową. Mimo że enzymy te są syntetyzowane przez wiele gatunków mikroorganizmów, to nadal poszukuje się nowych, środowiskowych szczepów zdolnych do syntezy zewnątrzkomórkowych lipaz. Celem przeprowadzonych badań była ocena aktywności lipolitycznej Proteus mirabilis w zależności od pH oraz temperatury. Aktywność lipolityczną analizowano w zakresie pH 4-9 oraz w temperaturach 5-60ºC. Do oznaczenia aktywności lipolitycznej posłużono się metodą miareczkową, a wyniki podano jako ilość uwolnionyc…
